You’re at a café, airport, motel, or client meeting.
You jump onto the free Wi-Fi, open your laptop or phone, and quickly check your emails. It feels harmless. Convenient, even. But this is one of the easiest ways for someone else to quietly get access to your webmail account.
Public Wi-Fi is, by its nature, shared. You have no idea who set it up, how it’s configured, or who else is connected to it. In many cases, you’re essentially shouting your information into a room full of strangers and hoping nobody is listening.
The biggest risk isn’t Hollywood-style hacking. It’s far simpler than that.
On unsecured or poorly secured Wi-Fi networks, it’s possible for someone else on the same network to intercept data as it moves between your device and the internet. If you log in to webmail, that can include usernames, passwords, session cookies, or login tokens. Once someone has those, they don’t need your password again – they can just walk straight in.
And email is the golden key.
If someone gets into your email, they can reset passwords for your website, social media, online banking, accounting software, and pretty much everything else you use. I’ve seen cases where attackers didn’t even change the password straight away. Instead, they quietly set up email forwarding rules so every message gets copied to them. The business owner has no idea until fake invoices start appearing or customers get strange replies.
What makes this worse is that webmail feels “safe”. It’s familiar. It’s something you do every day. But logging into email on public Wi-Fi is one of the highest-risk things you can do online.
So what should you do instead?
First, avoid logging into webmail on public Wi-Fi wherever possible. If it can wait until you’re on your home or office connection, wait.
If you absolutely must check email while you’re out, use mobile data instead of free Wi-Fi. Your phone’s 4G or 5G connection is far more secure than the average café network, even if the Wi-Fi has a password written on the wall.
Turn on two-factor authentication for your email. This means even if someone does get your password, they still can’t log in without a code from your phone. It’s one of the simplest and most effective security steps you can take.
Keep an eye on your email settings. Every now and then, check for strange forwarding addresses, filters you didn’t create, or login alerts you don’t recognise. These are often the first signs that something isn’t right.
Finally, remember this: convenience is usually the enemy of security. Public Wi-Fi is convenient, but it comes with strings attached. A few minutes of patience can save you weeks of clean-up, stress, and damage to your business reputation.
If you’re ever unsure whether your email or website setup is secure, ask. It’s much easier to lock the door properly than to deal with the mess after someone’s already walked in.
